Fiery Trapsmith

You can create fire-based ranger traps. 

Prerequisites: Pyrotechnicist 6 

Benefit: You learn to create a smoke trap and one other fire-based ranger trap of your choice. You can use these traps a total number of times per day equal to 1/2 your pyrotechnicist level + your Intelligence modifier. Once a trap is learned, it can’t be unlearned and replaced with a different type of fire-based trap. You cannot select an individual trap more than once. Each time you select this discovery, you learn a different fire-based ranger trap. You can only select from the following ranger traps: burning trap, exploding trap, fire trap, firework trap, summoned ally trap (fire creatures only), and toxic fumes trap.
